I'm basically attempting to make a "recipe type thing" where users can compile a bunch of rare materials to create an item called a "recipe," which they can then input into a furnace and output a certain material; however when smelting I wish for the "recipe" to remain in the furnace, and for the player to only need one (thus, once they've made the recipe they can make an amount of what the recipe creates that is only limited by the coal that they input.)
Is there a way for me to make my ingredient remain in the furnace? Perhaps a way to register when it's finished and then add a new one to the furnace? Additionally, is there a way for me to make it so that it requires more than 1 single coal per item? So that, for example, every 3 blocks of coal a new item is created?
Thanks!
